TYlPIEl-VVRITER` ATTACHMENT.

Specification of VLetters Patent.

Patented Aug. 11, 1914.1

Application led May 17, 1913. Serial No. 768,250.

` State of California, have invented new and useful Improvements in Type-Miter At-` tachments, of. which the following isa speciica'tion.

This invention relates to typewriterattachinents, and. particularly to typewriter attachments `to provide a support for a roll ffpaper, and the principal object is to provide a typewriter attachment with a traveling rollwhich moves cooperatively with the carriage.

Itisalfurther object te provide a type-4 wniter;1oll lcarrying attachment vthat is read-` ily secured to a machine of ,any type by a bracket and apair'of folding members.

In.` the drawingsv accompanying this specification and forming therewith the application for Letters Patent: Figure 1 is 'a rear v'wtofa typewriter with a roll carrying apparatus attached thereto, a portion of the roll-being shown in section. Fig. 2 is anend View of a writing machine and of the attachment. Fig. 3 is a detail plan viewfof one of the carriage folding members. Fig. 4 is a detail of thesevering means.

More specifically in the drawings, 5 designates the vrear portion of the frame on which is mounted the carriage 6 having the end frames 7. Secured to the rear portion ot the machine are the brackets 8 which support the rod 9 ,which acts as a supporting track for the roll supporting carriage 10. This carriage consists mainly of a horizontally disposed frame 11 having depending' therefrom a-plurality of brackets 4l2'. pairs of these brackets being* adapted to form bearings for the lrooved wheels 14 which rest upon the rod 9. The lower ends of these brackets are bent or formed with luesl 15 thereon which are brought together in such relation that it is impossible to lift the carriage from the rail, but the intervalbetween is suliicient to pass the brackets 8. Pivotally mounted at t ie ends of the frame are a pair of roll supports 16, which are preferably formed of sheet metal of the" gentral channeled configuration shown, the side thereof extending beyond the connecting `web adjacent the pivotal points so that theA lower; edge of the web rests upon the upper face-of Vthe frame 1,1, a pivot pin belng.

passed through a bore in the frame and the side plates below the end of the web. These supports are locked in position by means of spring` plates 18 which are secured near the -ends by means of rivets 19, the members being so disposed that the pressure exerted by the spring bearing on the inclined shoulders at theends of the frame 11 holds the supf port either in the vertical position shown in vfull lines in Fig. 1 or the open position shown in dotted lines. The upper and aljned ends of these supports are provided with oylindrical studs 19 which extend on either .side thereof, those facing one end forming journals for the roll .20 which is Vadapted t0 be revolubly mounted thereon, The outer end ofthe stud is provided with an annular ange 21, the studformiiig a bearngand the Harige acting as a stop engagedby the slotted hooked end 22 of the pivoted 'brace 28. This hook is adapted to embrace the stud and hold the latter in fixed relation to the support for the pivot 24- of this brace,

4, the support 25 being securely fastened to the end frame 7 of the carriage by means of fastenings 26. The roll 20 isa simple cylinvdri-c al -roll preferably of wood or light metal i havlng bores in its ends toA receivethe'triim I nions 19, these trunnionsbeing held in resilieiitwontact therewith by'means of the springs previously described, Mounted on t 1e roll are a pair 'of slidable sleeves 28 which are provided with flanges 29 which face each other and are adapted to form limitin means to hold the roll of aper 30 in proper relation to the roll. To ook these flanged sleeves in the proper relation thumb screws 31 are provided, which are mounted in threaded bores in a hub of the sleeve to take up against the roll 20 to secure the flanges in adjustable relation, y

lTo preserve the proper tension upon the paper roll a bearing plate 33 is provided which is hinged to a hinge plate .34 mounted centrally on the frame 11',-the hinge pin 35 of this bearing plate having encircled therearound a coiled spring 36W/hose ends are so disposed that they press this plate in resilient contact with-the roll of paper, 30.

From the roll `of papera sheet is carried down under the platen on the carriage 6 and up in the proper position above the carriage vwhere itis adapted to rest against a cutting plate 37 having a serrated edge 39 which is supported longitudinally on the carriage by means of a palr of brackets.

The operation of the attachment willbe readily understood from the drawings and 1 the description thereof.4 When it is desired to insert a roll of paper in .relation to the machine` the hooked braces 23- are` lifted from engagement with the studs 21 and a roll inserted between the studs 19 by spreading the supports 16 apart a suiiicientdistance to insert the latter into the roll when the braces 23 are again hooked in position,

- distance.

- thetrack 9. The paper roll advances with the platen as desired 1n the operation of the machine, and when the typing is completed the Apaper is pulled through until the desired point 1s reached and registered with the plate 37, when the paper can be severed by engaging it with this edge at this point, to tear off the desired amount. When it is not desired to use-the roll the braces 23 may be lifted and the roll bearing frame entirely rolled oli of'l the rod 9 and used in another machine, there 'remaining only the brackets 8 and the braces 23, the latter of which may be folded down and not materially aHect the operation or appearance of the machine.

What Iclaimis: l

1. In a typewriter attachment in combina tionwith a typewriting machine having a reciprocating carriage, ,of a rail sup orted 4adjacent thereto, a movable frame a apted l .to travel on said rail, a plurality of movable of said carriage,

supports secured to said frame, trunnions on sald supports, a rol/l having bores adapted to receive said trunnions and a Spring t0 press said supports into engagement with said roll.

. 2. In a typewriter attachment in combination with a typewriter having a movable carriage, of a' track mounted adjacent and in parallel relation with the path of movement a frame mounted on wheels supported on said track, a plurality of resiliently mounted supports mounted on'said movable frame, a roll adapted to carry a roll of paper mounted' on said supports, and

means to connect said roll and its supports "I to move with the carriage of said typewriter,

3.' Ina typewriter attachment in combination with a typewriter having a movable 'carriage thereon, a track mounted adjacent to andv parallel with the path of movement of said carriage, a frame provided with wheels adapted to be supported and travel on said track, pivoted supports mounted on the ends of said frame, spring actuated means to hold said support-s in rigid relation to said frame,

studs mounted on said supports, flanges on said studs', and slotted hooks hinged to said movable carriage with the slots thereon adapted to embrace said flanges whereby said supports and frame may be connected to said movable carriage.

In witness that I claim the foregoing I lhave hereunto subscribed my name thislOth day of May, 1913. l
